BACKGROUND

1. Technical Field

The present disclosure relates to a building with temperature regulating system and its temperature regulating method and more particularly to a building with temperature regulating system and its temperature regulating method which employs forced convection to reduce temperature.

2. Related Art

Generally, greenhouse is used for providing an ideal environment for the growth of a large amount of plants. A typical greenhouse is composed of fencing and top frames, and a covering body is wrapped around the fencing and the top frames, so that a closed space is formed inside the greenhouse. A greenhouse with the aforementioned structure can prevent bugs and mosquitoes from entering into a plant area of the greenhouse, and an ideal temperature can be maintained inside the greenhouse. Nevertheless, being affected by an outdoor temperature and under the sunlight, the temperature inside the greenhouse will increase, if heat can not be dissipated appropriately to regulate the temperature, it will be harmful for the growth of plants due to an increased temperature inside the greenhouse.

Therefore, vents or airways are additionally disposed to regulate the temperature inside the greenhouse, in order to prevent the temperature inside the greenhouse to get too high and therefore, to harm the plants inside the greenhouse. This type of greenhouse with vents includes a first waterproof layer covered on the greenhouse, at least one vent disposed on the first waterproof layer, a covering element cooperating with the vent and a second waterproof layer covered on the covering element. The covering element has a pivotal pole which is pivotable, and a free pole rotating between a closed position and an air ventilating position by using the pivotal pole as its shaft. When the free pole is at the closed position, the covering element is closely fitted with the vent, and the second waterproof layer can prevent external air from entering into the greenhouse through an air permeable layer from the vent. When the free pole is at the air ventilating position, a large amount of external air can be entered into the greenhouse from the vent in order to regulate a temperature inside the greenhouse.

The way of disposing additional vents to regulate the temperature inside the greenhouse mainly utilizes natural convection to achieve heat exchange between indoor and outdoor environments of the greenhouse. However, reducing the temperature timely still cannot be achieved by merely disposing additional vents. Accordingly, besides the additionally disposed vents, fan sets can also be disposed in the greenhouse, so that forced convection generated by the fan sets can reduce the temperature inside the greenhouse speedily, and therefore, an ideal temperature regulating effect can be achieved.

However, when the temperature outside the greenhouse is too low, and if external air with a low temperature introduced into the greenhouse by forced convection is blown on the plants inside the greenhouse directly, the plants may be suffered from chilling injury or their quality of growth will be affected.

DETAILED DESCRIPTION

In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. It will be apparent, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are schematically shown in order to simplify the drawing.

Some embodiments of the disclosure provides a building with temperature regulating system and its temperature regulating method by which plants inside a greenhouse can be avoided from being contacted directly with external air with a low temperature, and the plants can be prevented from suffering of chilling injury.

FIG. 1 is a structural illustration of a building with temperature regulating system according to an embodiment of the disclosure.

A greenhouse for growing potted plants 20 is used as an example for a building with temperature regulating system 10 of the disclosure, but it should not be construed as a limitation to the disclosure. For instances, the building with temperature regulating system 10 of this embodiment can also be applied in other industries such as stock raising.

The building with temperature regulating system 10 comprises a main construction 100, a working platform 110, a first water wall 131 and a first fan 141. The main construction 100 can be constructed with steel frames and canvas, or cement and reinforcing steel bars, but the disclosure is not limited to them. The main construction 100 has a bottom surface 103 as well as a first side wall 101 and a second side wall 102 disposed on two opposite sides of the bottom surface 103 respectively, and the first side wall 101 has a penetrated air passage 120.

The working platform 110 of this embodiment is disposed inside the main construction 100 and is set up on the bottom surface 103. The working platform 110 is disposed between the first side wall 101 and the second side wall 102, and the working platform 110 has a supporting surface 111. A culture bed of greenhouse is used as an example for the working platform 110, and therefore the supporting surface 111 of the working platform 110 is used for placing the potted plants 20 inside the greenhouse.

Furthermore, the first water wall 131 is disposed on the first side wall 101, the first water wall 131 can be opened for ventilation, or with water flowing down while being opened in order to increase humidity and to reduce the temperature. Because water wall is a conventional device, related and detailed structures of the first water wall 131 will not be mentioned herein.

The air passage 120 in this embodiment penetrates the first side wall 101, and the air passage 120 is used to connect the space inside the main construction 100 to the ambient. The air passage 120 can be closed or opened. When the air passage 120 is opened, external air is capable of entering into the main construction 100 through the air passage 120. Furthermore, the air passage 120 is disposed below the first water wall 131, and a maximum height D2 between the air passage 120 and the bottom surface 103 is smaller than a height D1 between the supporting surface 111 and the bottom surface 103. Due to the height of the air passage 120 relative to the supporting surface 111, when external cold air is introduced into the main construction 100 through the air passage 120, the cold air will not blow on the potted plants 20 on the working platform 111 directly, and thereby the potted plants 20 can be prevented from suffering chilling injury.

Furthermore, the first fan 141 is disposed on the second side wall 102, and the air generated by the first fan 141 is corresponding to the working platform 110. More specifically, air inside the main construction 100 is discharged outside the main construction 100 by the first fan 141. Furthermore, a height of an axis of the first fan 141 in this embodiment from the bottom surface 103 is roughly the same as the height of the supporting surface 111 from the bottom surface 103, but it should not be construed as a limitation to the disclosure. The height of the axis of the first fan 141 from the bottom surface 103 can be adjusted by any person of average skill in the art according to practical requirements.

Referring to FIG. 1, in this embodiment or other embodiments, the building with temperature regulating system 10 can further comprise a second water wall 132. The second water wall 132 is disposed on the first side wall 101 between the first water wall 131 and the air passage 120.

Furthermore, in this embodiment or other embodiments, the building with temperature regulating system 10 can further comprise a second fan 142. The second fan 142 is disposed on the second side wall 102 and is above the first fan 141. The air inside the main construction 100 is discharged outside the main construction 100 by the second fan 142.

Furthermore, in this embodiment or other embodiments, the building with temperature regulating system 10 can further comprise a heater 160. The heater 160 is disposed inside the air passage 120, but the disclosure is limited by it. For examples, the heater 160 can be disposed in a path of air passing through the air passage 120. The heater 160 is used for increasing the temperature of cold air passing through the air passage 120, and thereby the potted plants 20 can be prevented from suffering chilling injury because of the cold air.

Furthermore, in this embodiment or other embodiments, the building with temperature regulating system 10 can further comprise a first temperature sensor 151, a second temperature sensor 152 and a third temperature sensor 153. The first temperature sensor 151 and the second temperature sensor 152 are disposed on the working platform 110, and the first temperature sensor 151 is nearer to the first side wall 101 than the second temperature sensor 152. More specifically, the first temperature sensor 151 and the second temperature sensor 152 are disposed on two opposite sides of the working platform 110 respectively, and the first temperature sensor 151 is nearer to the first side wall 101, while the second temperature sensor 152 is nearer to the second side wall 102, and the potted plants 20 are disposed between the first temperature sensor 151 and the second temperature sensor 152. The first temperature sensor 151 and the second temperature sensor 152 monitor temperatures at two opposite ends of the potted plants 20 respectively. More specifically, temperatures of all the areas inside the main construction 100 are different, and therefore by disposing the first temperature sensor 151 and the second temperature sensor 152, changes of a temperature gradient between the first temperature sensor 151 and the second temperature sensor 152 can be monitored precisely.

The positions of the first temperature sensor 151 and the second temperature sensor 152 are not fixed, and the positions of the first temperature sensor 151 and the second temperature sensor 152 can be adjusted according to positions of areas for placing the potted plants 20, provided that the potted plants 20 are disposed between the first temperature sensor 151 and the second temperature sensor 152, and the first temperature sensor 151 is nearer to the first side wall 101 than the second temperature sensor 152.

Furthermore, the third temperature sensor 153 is disposed outside the main construction 100 for detecting the temperature outside the main construction 100.

Referring to FIGS. 2 to 6 and cooperating with FIGS. 7A and 7B at the same time, FIGS. 2 to 6 are illustrations of an operation of a control method of a building with temperature regulating system according to an embodiment of the disclosure. FIGS. 7A and 7B are flow charts of a control method of a building with temperature regulating system according to an embodiment of the disclosure.

The control method of the building with temperature regulating system 10 includes following steps.

Referring to FIGS. 2 and 7A, firstly, the potted plants 20 between the first temperature sensor 151 and the second temperature sensor 152 are disposed in the building with temperature regulating system 10, and an upper temperature limit and a lower temperature limit (S1) are limited. For this embodiment, the range between the upper temperature limit and the lower temperature limit can be ambient temperatures for an optimum growing condition of the potted plants 20. For example, the upper temperature limit rates be 30° C. and the lower temperature limit can be 24° C.

Then, if the temperature detected by the first temperature sensor 151 or the second temperature sensor 152 is higher than or equal to the upper temperature limit (S2) is determined. If the temperature detected by the first temperature sensor 151 or the second temperature sensor 152 is higher than or equal to the upper temperature limit, whether an outdoor temperature outside the main construction 100 is lower than the lower temperature limit by the third temperature sensor 153 (S3) is detected. If the outdoor temperature detected by the third temperature sensor 153 is lower than the lower temperature limit, the first fan 141 is turned on and the air passage 120 is opened to carry out ventilation and temperature reduction (S4).

More specific on the abovementioned control steps, wherein the temperature detected by the first temperature sensor 151 or the second temperature sensor 152 is used as a reference for determining a main temperature inside the main construction 100. Therefore, when a temperature detected by the first temperature sensor 151 or the second temperature sensor 152 is higher or equal to the upper temperature limit (30° C.), it represents that the temperature inside the main construction 100 has reached or over a highest temperature for the optimum growing condition of the potted plants 20. At this point, an external air must be introduced into the main construction 100 to reduce the temperature inside the main construction 100. Before introducing the external air, information on a temperature of the external air is acquired by using the third temperature sensor 153. For example, when the temperature (e.g. an outdoor temperature in winter is 15° C.) outside the main construction 100 detected by the third temperature sensor 153 is lower than the lower temperature limit (24° C.), it represents that the outdoor air is too cold. At this point, the first fan 141 is turned on and the air passage 120 is opened to carry out ventilation and temperature reduction as shown in FIG. 2. When the external cold air enters the main construction 100 through the air passage 120, an air formed by the external cold air passes through below the working platform 110, and then it is discharged outside the main construction 100 by the first fan 141. Thereby, the temperature inside the main construction 100 is reduced by the external cold air, and the potted plants 20 are not in the direct path of the air of the external cold air. Therefore, the problem of growing quality of the potted plants 20 being affected by cold air can be prevented.

Then, it is determined that if a temperature detected by the first temperature sensor 151 is lower than the lower temperature limit (S5). If it is lower, the rotating speed of the first fan 141 is reduced or the heater 160 is turned on (S6). If it is not lower, no change is made, and the temperature with the first temperature sensor 151 is monitored continuously. More specifically, if the temperature detected by the first temperature sensor 151 is lower than the lower temperature limit (24° C.), it represents that the flow rate of the air of the cold air is too high or the temperature is too low, and the temperature at the end of the working platform 110 closed to the first side wall 101 is too low. Thus the potted plants 20 on the working platform 110 closed to the first side wall 101 may suffer from chilling injury. Therefore, once a temperature detected by the first temperature sensor 151 is lower than the lower temperature limit (24° C.), the rotating speed of the first fan 141 is reduced immediately, so that the flow rate of the air of the external cold air is reduced in order to increase the temperature at the end of the working platform 110 closed to the first side wall 101. Or, by turning on the heater 160 to increase the temperature of the air of the cold air, the potted plants 20 can be prevented from suffering chilling injury or their quality of growth can be prevented from being affected.

Referring to FIGS. 3, 4, 7A and 7B, after detecting if an outdoor temperature outside the main construction 100 is lower than the lower temperature limit by the third temperature sensor 153 (S3), if the outdoor temperature outside the main construction 100 detected by the third temperature sensor 153 is higher than or equal to the lower temperature limit (24° C.), it is further determined that if the outdoor temperature outside the main construction 100 detected by the third temperature sensor 153 is lower than the upper temperature limit (S7). If the outdoor temperature outside the main construction 100 is lower than the upper temperature limit, the air passage 120 is closed, the second fan 142 is turned on and the first water wall 131 is opened to carry out ventilation and temperature reduction (S8). For example, if the outdoor temperature (e.g. an outdoor temperature in spring and autumn is 25 to 27° C.) outside the main construction 100 detected by the third temperature sensor 153 is higher than or equal to the lower temperature limit (24° C.), and lower than the upper temperature limit (30° C.), it represents that the outdoor temperature is a suitable ambient temperature for the growing of the potted plants 20. At this point, the air passage 120 is closed, the second fan 142 is turned on and the first water wall 131 is opened, so that the external air enters the main construction 100 through the first water wall 131 directly to reduce the temperature, and it is discharged outside the main construction 100 by the second fan 142 as shown in FIG. 3.

Furthermore, after the ventilation and temperature reduction are carried out by the second fan 142 and the first water wall 131 for a time interval, it is determined that if a temperature detected by the second temperature sensor 152 is still higher than or equal to the upper temperature limit (S9). If the temperature detected by the second temperature sensor 152 is lower than the upper temperature limit, keep monitoring the temperature by the second temperature sensor 152 and maintaining a fixed rotating speed of the fan. If the temperature detected by the second temperature sensor 152 is higher than or equal to the upper temperature limit, then the rotating speed of the fan is increased and it is determined that if the temperature detected by the second temperature sensor 152 is lower than the upper temperature limit. When the rotating speed of the fan is adjusted to the highest gradually and if the temperature detected by the second temperature sensor 152 is still higher than or equal to the upper temperature limit, then the second water wall 132 is opened (S10). More specifically, if the ventilation and temperature reduction are carried out by the second fan 142 and the first water wall 131 for a time interval, for example, five minutes, ten minutes or fifteen minutes, and when the rotating speed of the fan is adjusted to the highest, and if the temperature detected by the second temperature sensor 152 is still higher than or equal to the upper temperature limit, it represents that effects of ventilation and temperature reduction are not ideal. Therefore, the second water wall 132 can be further opened to increase the flow rate of the external air entering into the main construction 100 in order to enhance the effects of ventilation and temperature reduction as shown in FIG. 4.

Referring to FIGS. 5, 6, 7A and 7B, after the step of detecting if an outdoor temperature outside the main construction 100 is lower than the lower temperature limit by the third temperature sensor 153 (S3), if the outdoor temperature outside the main construction 100 detected by the third temperature sensor 153 is higher than or equal to the lower temperature limit (24° C.), then it is further determined that if the outdoor temperature outside the main construction 100 detected by the third temperature sensor 153 is lower than the upper temperature limit (S7). If the outdoor temperature outside the main construction 100 is higher than or equal to the upper temperature limit, the second fan 142 is turned on and the first water wall 131 is opened, and water flows down on the first water wall 131 to carry out ventilation and temperature reduction (S11). For example, if the outdoor temperature (e.g. an outdoor temperature in summer is 32° C.) outside the main construction 100 detected by the third temperature sensor 153 is higher than or equal to the upper temperature limit (30° C.), it represents that the outdoor temperature is over an upper ambient temperature limit suitable for the growing of the potted plants 20. At this point, an effect of temperature reduction still can not be achieved even if the external air is introduced inside the main construction 100 directly. Therefore, the second fan 142 is turned on and the first water wall 131 is opened, and water flows down on the first water wall 131 to carry out ventilation and temperature reduction at the same time. Water is discharged and flows down from a water supply device on the first water wall 131, so that the water current is flowed down along the first water wall 131 and therefore, the first water wall 131 is moistened. The water flowing down on the first water wall 131 can be recycled to be used repeatedly. Therefore, when the external air passes through a through hole on the moistened first water wall 131, a large amount of heat is absorbed by evaporation of the water, so that a temperature of the air passing through the first water wall 131 can be reduced. After the step of letting water to flow down on the first water wall 131, the temperature of the external air is reduced first before entering the main construction 100 to be further cooled, and is discharged outside the main construction 100 by the second fan 142 as shown in FIG. 5.

Furthermore, after the ventilation and temperature reduction are carried out by the second fan 142 and the first water wall 131 for a time interval, it is determined that if a temperature detected by the second temperature sensor 152 is still higher than or equal to the upper temperature limit (S12). If the temperature detected by the second temperature sensor 152 is lower than the upper temperature limit, then the second temperature sensor 152 continuously monitor the temperature and the fan maintains a fixed rotating speed. If the temperature detected by the second temperature sensor 152 is still higher than or equal to the upper temperature limit, then the rotating speed of the fan is increased and it is determined that if the temperature detected by the second temperature sensor 152 is lower than the upper temperature limit. When the rotating speed of the fan is adjusted to the highest gradually and if the temperature detected by the second temperature sensor 152 is still higher than or equal to the upper temperature limit, then the second water wall 132 is opened and water flows down on the second water wall 132 (S13). More specifically, if the ventilation and temperature reduction are carried out by the second fan 142 and water flows on the first water wall 131 for a time interval, for example, five minutes, ten minutes or fifteen minutes, and when the rotating speed of the fan is adjusted to the highest, and if the temperature detected by the second temperature sensor 152 is still higher than or equal to the upper temperature limit, it represents that effects of ventilation and temperature reduction are not ideal. Therefore, the second water wall 132 can be further opened and water can flows down on the second water wall 132 to increase a flow rate of the external air entering into the main construction 100 in order to enhance the effects of ventilation and temperature reduction as shown in FIG. 6.

According to the temperature regulating method of the building of the above-mentioned embodiment, by having a maximum height between the air passage and the bottom surface smaller than a height between the supporting surface of the working platform and the bottom surface, when the external cold air is introduced into the building through the air passage, the cold air will not blow the potted plants on the working platform directly, and thereby the potted plants can be prevented from suffering chilling injury or their quality of growth can be prevented from being affected. Furthermore, by using the control method of the embodiment, different steps of ventilation and temperature reduction can be carried out for the building with temperature regulating system according to different external temperatures in spring, summer, autumn and winter, in order to ensure that the temperature inside the building can be maintained within an ideal range of controlled temperatures.
